I was planning to use a Parasound Halo A21 / A51 combo to drive my Triad speaker system. However, I want to use less rack space so I'm now looking for a single 7 channel amp that would be comparable to the Halo combo in the following ways:

Price on the used market

Wattage into 4 ohms (400 watts or more)

Sound quality

Fit and finish

Features and inputs

I will be driving Triad Platinum LCR and Center, and Silver Surrounds for mostly home theater use.

I know sound is subjective so I'm just looking for some feedback on good viable options I should check out. I also know that this approach would provide more power than I need for the surrounds, but I'm fine with that as I would like to get a single unit.

I'm not looking for bargain options, but products with good price points in the secondary market for a very good product.

I have not selected a processor yet, but will likely be considering something like the Lexicon MC-12HD when the time comes. so the Lexicon amps are one viable option. I'm looking for other good options though so please share your thoughts.
